Pixi Spine problem

Recommended Posts

In case you use premultiplied alpha in png textures, specify it for pixi: dig out which baseTexture it uses and specify "mySpineResource.spineAtlas.pages[0].baseTexture.pmaMode = PIXI.ALPHA_MODES.PMA"

We added this feature to pixi but didn't propagate it to pixi-spine.

OK, confirmed, it works in latest spine-ts but not in pixi-spine.

Maybe I can look at it in weekend, maybe not.

There's an issue https://github.com/pixijs/pixi-spine/issues/318 with skins, maybe the same problem appears in your case. Yes, I couldn't fix it since november, it requires a total rewrite of "Spine.js" "update" function.

If you want to investigate yourself, clone https://github.com/EsotericSoftware/spine-runtimes/tree/3.8/spine-ts and put your demo in webgl/examples. They dont have JSON by default there, so I had to modify loadSkeleton method a bit:

// .. load

function init () {
   //...
	assetManager.loadText("assets/Down.json");
	assetManager.loadTextureAtlas("assets/Down.atlas");
    //...
}

function load() { 

  //...
    skeletons["Down"] = loadSkeleton("Down", "run", false, undefined, true);
}

function loadSkeleton (name, initialAnimation, premultipliedAlpha, skin, isJson) {
    //...

	var skeletonBinary = new spine.SkeletonBinary(atlasLoader);
	var skeletonJson = new spine.SkeletonJson(atlasLoader);

	var skeletonData = isJson ?  skeletonJson.readSkeletonData(assetManager.get("assets/" + name + ".json"))
					: skeletonBinary.readSkeletonData(assetManager.get("assets/" + name + ".skel"));
    //...
}
